Definitions

  • the invention relates to a process for producing a paint having a desired colour, based on the use of base paint and pigment pastes.
  • FR-A-1,178,404 discloses a process for preparing a synthetic paint by mixing a pigment concentrate containing 37-72% by weight of pigment, 14-21% by weight of binder resin, and an organic solvent with a clear base paint containing 13-40% by weight of a binder resin and further constituents.
  • Paint producing systems are generally known under the name of colour mixing system and are marketed by virtually every large print manufacturer.
  • the equipment, pigment paste and base paints can be found in distribution centres and shops. These are systems which are based on a fairly large number of base paints per type of product.
  • Standard pigment pastes are so-called “universal” and are used to tinge both synthetic base paints and water-reducible base paints. In addition to pigment, they contain thickeners, water, organic solvents, such as glycols, and auxiliary agents for adjusting the total balance.
  • a quantity of binder for example, of alkyd resin
  • the base paints have a composition which is dependent on the intended application. Thus, a distinction is made between base paints for high-gloss paints, silk-gloss paints, latex paints, chlorinated rubber paints, opaque staining paints, transparent staining paints, etc. Such base paints then always contain virtually the entire quantity of binder, for example alkyd resin, required. Because the pigment paste can be added only in a limited quantity, a large number of base paints are necessary which already contain a quantity of pigment. The addition of the pigment pastes then adjusts the colours to the correct tones. In general, 5-10 base paints per type of paint are employed, that is to say, 5-10 base paints for high gloss, 5-10 base paints for silk gloss etc. Colours for base paints are therefore, for example, white, midwhite, clear, yellow, red, blue and the like.
  • binder for example, alkyd resin
  • the shelf life of the pigment pastes is good and the applied, ready paint layer does not exhibit any accelerated ageing either.
  • the base paint and pigment paste are combined, in a proportion which depends on the degree of filling per type of product, and on whether a synthetic or a water reducible paint is produced.
  • a proportion which depends on the degree of filling per type of product, and on whether a synthetic or a water reducible paint is produced.
  • the different types of base paints may be categorized as follows, the stated quantities of pigment paste being advisable.
  • Synthetic paints Description Base paint Pigment paste. vol.% - high-gloss varnishes White ⁇ 7.5 - industrial varnishes Clear 45 - satin-gloss varnish paints White ⁇ 7.5 - opaque primers Clear 30 chlorinated rubber paints
  • Synthetic paints Description Base paint Pigment paste. vol.% - other solvent-containing White ⁇ 7.5 paints (including multi- Clear 30-45 component paints) Water-reducible paints Description Base paint Pigment paste.
  • Base paints for the synthetic group are paints which are borne by organic solvents.
  • the base paints are made up with water-borne binders.
  • the synthetic pigment paste contains, as carrier material, a considerable portion of binder (for example, alkyd resin), while the pigment paste for the aqueous systems contains a considerable percentage (15-45 % by weight) of water-miscible glycols.
  • the old philosophy of tinting a paint has essentially been abandoned, but the starting point is now two components which together form the paint.
  • the pigment paste no longer in fact contains the liquid-borne pigment alone, but also a considerable quantity of binder.
  • up to 45 % by volume of pigment paste is expediently used for synthetic base paint, calculated on the basis of the total of pigment paste and base paint. A considerably larger ratio than was standard hitherto. Up to 20 % by volume of pigment paste (synthetic) or 7.5 % by volume of pigment paste (water-reducible) respectively was standard.
  • Pigment pastes may, for example, have the composition as described in the table entitled Examples and Compositions and in the example of the preparation of a pigment paste.
  • any colour can be obtained by means of two base paints per type of product by means of a colour mixing machine making use of prepacked quantities of base paint and adding to the prepacked base paint both volumetrically and gravimetrically.
  • the "white” base paints contain a white pigment as colour-determining constituent.
  • the "clear” base paints do not contain any, or contain few, colouring constituents.
  • the pigment pastes are matched mutually to each other in a manner such that, for the diverse types of final product, the quality of the paint is not affected in an adverse sense in terms of colour.
  • Alkyd resin is suitable as binder both for use in the base paint and in the pigment paste.
  • binders for paints and pigment pastes can also be used.
  • suitable binders are epoxy resin and a polyurethane.
  • the pigment can be taken up in the hardener or in the resin.
  • the pigment-containing component is then added to the resin component in the tin.
  • the old philosophy was to tint the base paints with a small amount of pigment paste. To achieve sufficient hiding power, many base paints were required in different colours.
  • the new philosophy (the system developed here according to the invention) is few base paints (two). To obtain sufficient hiding power a large amount of pigment paste is now necessary, in particular, for the clear base paint.
  • the standard ratios contain only a few per cent of colouring paste compared with 10 to 45 % by volume (in the two-base-paint system) for the clear base paint.
  • the number of base paints in the old philosophy was approximately 5 to 10 per type of product.
  • pigment pastes and base paints can be prepared in the usual manner.
  • suitable compositions are the following:
  • Example of a white base paint for an opaque semi-gloss outdoor stain Description Quantity Preparation Binder, 60% 21.00 weigh out Pigment moistener 0.40 add and mix Rheological additive 0.40 add and mix Titanium dioxide 27.50 add during mixing Filler 4.00 add during mixing disperse to desired fineness Solvent 4.50 add and stir in Binder, 60% 31.00 add during mixing Drier 1.50 add during mixing Anti-skinning agent Binder, 60% 0.20 add during mixing solvent 9.50 adjustment to viscosity and colouring power
  • Example of a green pigment paste Description Quantity Preparation Binder 70% 37.00 weigh out Solvent 2.00 add during mixing Pigment moistener 0.40 add during mixing Rheological additive 1.50 add during mixing Chromium oxide green 35.00 disperse to required fineness Binder, 70% 20.00 add during mixing Anti-skinning agent 2.00 add during mixing Solvent/binder 2.10 grind to colouring power
  • Example of an opaque outdoor stain in a green full tone - Clear base paint 70 % by volume - Pigment paste, green 30 % by volume
  • the filler is absent (high gloss) or is present to a considerable extent (silk gloss).
  • the synthetic paints prepared according to the invention were tested for shelf life and compared with paint prepared by the universal system.
